To all whom it may concern:

Be it known, that I, Josnrn LHPOTTER, a citizen of the United Statesresiding at Indianapolis, in the county of Marion and State of Indiana,have invented: a new and useful Dumping vExc ating-,13ucket, of whichthe following is a specification, reference being had to theaccompanying drawings and totheletters and figures of reference markedthereon.

This invention relates to an excavating with various. means for hoistingand carrying the bucket, the 1nvent1on havmg reference ing and carryingthe bucket and permitting it to be manipulated so asto quickly d gchargeits load; the invention havingreference also to improved means foroperating and controlling the bucket in operation. The invention relatesalso fu ther tothe apparatus disclosed in my prior application forLetters Patent filedJune 2Q 1914, Serial No. 846,270, thepresentapplicationbeing a continuation of said prior applicationin so far .asthe subject matteriscommon toboth applications.

An object of the inventioni s to provide an improved dumpingxcxcavatingtbucket that shall be so constructed asto becapable of being convenientlyand1 quickly operated and controlled, at

A practical embodiment ofthe invention includes a suitable bucketbody'which preferably comprises a bottom '1 of suitable construction andform, a back or rear end 2, a topportion d connectedwith the back, sidemembers 4: and 5 connected to the bottom andthe back andalso to the topportion'and having forwardly-extending upper portions, and thetransverse member 6 connected with the tops of the forward portions ofthe side members. For the purposes of the present invention the member60f the bucket body preferably is provided with longitudinally centrallyarranged ribs 7 which support a sheave Sat the forward portion thereof,the ribs having apertures 9 rearward of the sheave. A separateunyielding slide bar or balancing bar 10 is secured tothetop portion 3and also to the transverse member, 6

When the carriageis drawn forward and stopped the cable 29. is caused to continue forwardmovement so as to draw the branch 32, or the branch is independentlydrawn forward, if necessary to over-balance the bucket body forwardly,

after which the cable or line 29 is slackened to permit the bucket toturn over forwardly and discharge its load, which position is seen inFig. 2. In the case of the bucket having the rigid handle the branch 32draws the handle forward over the roller 19 until the crook 38 isbrought on to the roller so as to support the bucket as it tilts forwardand discharges its load. In either case the bucket is caused to turnover forwardly with promptness so as to quickly discharge its load. Thebucket is returned to the excavation and the operations repeated as maybe required.

Then the bucket is required to handle sticky mud or soil which mayadhere to the bucket in attempting to discharge the load, it will be anadvantage to permit the yoke 12 to freely slide along the bar 10, andpermit the cable 32 to draw the yoke forward to the member 6 whenfilling the bucket, so that when the bucket is turned to an inclinedangle to begin discharging its lead the bar 10 will slip through theyoke and let the bucket rapidly descend until the rear portion 3 of thebucket engages the yoke and causes the bucket to abruptly stop in itsdescent, which jars the load loose from the bucket and insures readydischarge of the load. A similar result is obtained in the use of thebar 40 when the stop portion 38, suddenly stopped on the roller 19,causes a jar which dislodges the load.

Having thus described the invention, what is claimed as new is 1. Anexcavating bucket including a bucket body with a sheave on its forwardportion, a straight handling bar secured to the forward and rearwardportion of the body, a handling cable connected with the rearwardportion of the body and also connected with the handling bar to permitslip of the bar relatively to the cable connection, and a controllingcable extending under the sheave and connected to the handling cableadjacent to its connection with the bar.

2. An excavating bucket comprising a bottom and a back end and sidesconnected thereto, the upper portions of the sides extending forwardbeyond the lower portions thereof and having a transverse memberthereon, a longitudinal rib rigid on the transverse member and havingapertures therein, ahandling cable connected with said back end and inone of said apertures with the rib, and means for slidingly connectingthe cable with the transverse member when disconnected from the rib.

3. In excavating apparatus, the combination with a roller provided witha carriage device for carrying the roller, and a scoop body, of a sheavemounted on the forward portion of the scoop body, a balancing barsecured to said body, a handling cable connected with the rearwardportion of said body and extending over said roller, means forconnecting the cable either to the forward portion of said body or tosaid bar, and a controlling cable guided by the carriage device andextending under said sheave to and connected with the handling cable.

4. In excavating apparatus, the combination of a carriage, a wheel tosupport the carriage, a sheave and a roller spaced a long distance apartin the carriage, a drag bucket body having a transverse forward topmember on its sides, a straight balancing bar secured rigidly to saidmember and also to the rear portion of the bucket body, a guide devicemounted on said member, a handling cable connected with the rear portionof the bucket body and also with said bar and extending over saidroller, and a controlling cable connected to said handling cable betweensaid roller and said bar and extending directly to and under said guidedevice and thence to and over said sheave.

5. In excavating apparatus, a drag bucket comprising a bottom and sidesand also a back end, a transverse member secured to said sides, astraight balancing bar having one end rigidly secured to the under sideof said member and its opposite end rigidly connected with said backend, a pair of ribs rigidly secured on the upper side of said member andhaving apertures therein, a yoke slidingly arranged on said bar, and ahandling cable connected with the back end of said bucket and having ashackle to be connected with either the yoke or the apertures in saidribs.

In testimony whereof, I affix my signature in presence of two witnesses.
